Specification of Letters Patent.

Patented Dec. I2, Inuit Application filed June 12, 1916. Serial No. 103,289.

To all whom it may concern:

Be it known that I, ERNEST L. Woons, a citizen of the United States, residin at Farmer, in the county of Hanson and tate of South Dakota, have invented certain new and useful Improvements in Motor-Vehicle- Locking Devices, of which the following is a specification. i

This invention relates to locking devices for motor vehicles of the type in which the starting of the engine is dependent upon the operation of one or more push buttons or of a foot treadle.

The object of the invention is to provide a simply constructed lock of this character which may be readily and quickly removed in its entirety from the car and quickly applied when desired.

Another object of the invention is to so construct a lock of this character that a padlock for securing the device in operative position may be quickly applied and removed. a

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing: Figure 1 represents a front elevation of a portion of a dashboard or other support showing this improved locking device applied to a push button; Fig. 2 is a longitudinal vertical section thereof with the device shown in closed operative position; Fig. 3 is a rear elevation of the device detached with the padlock removed; Fig. 4 is a side elevation thereof; and Fig. 5 is a plan view.

In the embodiment illustrated the device constituting this invention is shown applied to a push button B having the usual shoulder S and mounted in an upright casing w'all W, and to start the car this push button B must be operated.

The locking device comprising the invention consists of a two-part clamp, the sections 1 and 2 of which are in the form of substantially rectangular plates of sufficient thickness when placed between the shoulder S of the push button B and the casing W to prevent said button from being actuated.

These plates 1 and 2 each have one end chamfered on one face as shown at 3 and each is provided with a semi-circular ear 4:

which projects laterally from the inner or meeting edge adjacent the chamfered por-' tion thereof. The chamfered portion 3 of each section issemi-circular and of a size to receive the semi-circular ear of the other sectionso that when thesections are assembled, hlnge knuckles will be formed by these ears which are connected by a'rivet 5 forming the pivot or pintle of the hinge. The chamfered portion or seat 3 of 'one'section corresponds in depth to the thickness of the ear 4 of the other section as that when the sectlons are connected both. faces of one plate will be flush with the corresponding faces of the other.

The meeting edges of the plates 1 and 2 are provided with semi-circular recesses 6 positioned to register with each other when and .form a circular opening 7 which is designed to fit snugly around the stem 8 of the push button when the device is applied (see Figs. 1 and 2). The meeting edges the sections are closed as shown in Fig. 3

of the sections 1 and 2 diverge near their 1 free ends forming a II-shaped recess8 when the plates are in closed operative position for a purpose to be described.

Substantially lL-shaped keeper members 9 and 10 are secured at the free ends of their short arms to the outer or front face of the closed operative position, said lock 14 being of any suitable or desiredconstruction. The

keeper members 9 and 10 being of L-Shaped construction and the short arms thereof secured at their free ends to the outer faces of the plates 1 and 2, spaces the overlapping 13 of the lock 14, and the cutting away of the outer ends of the meeting edges of the y vents all possibility to plates 1 and 2 affords additional space for this purpose.

In the use of this improved locking device, the two sections 1 and 2 are swung apart a sufiicient distance to permit them to slip down over the stem of the push button between the shoulder S and the casing wall W, which is usually the dash board of the car, and the sections are then swung inwardly toward each other until their meeting edges abut with the aperture 7 snugly fitting the stemof the push button, whereby the button is prevented from being moved inward. These push buttons are usually employed for operating an ignition system of an automobile so that when the locking device is engaged with said button it preof the spark being produced for starting the car.

- While this device has been described as applied to a push button of an ignition system for automobiles, obviously it may be used in connection with any push button which it is desired to lock, or with any treadle having a shoulder and a stem.

I claim:

A locking device of the class described comprising a two-part clamp. composed of a pair of substantially rectangular pivotally connected plates arranged edge to edge with said edges abutting when the plates are closed, eachplate having alaterally extending semi-circular apertured ear at one end on its abutting edge, said ears being arranged in lapping ,relation, the opposed faces of the plates adjacent said ears being chamfered to form semi-circular seats, the bottom of the seat of each plate being flush with the inner face of its ear and of a depth corresponding to the thickness of the ear on the other plate and adapted to receive said ear when the plates are assembled whereby both faces of one plate will be flush with the corresponding faces of the other, a transverse pivot connecting said ears, the free ends of said plates having their opposed edges diverging outwardly from a point spaced from their terminals to form a space between them when closed, said abutting plate edges being provided with registerln recesses between their pivotally connected and free ends, and L-shaped keeper members, one secured at the free end of one arm to one plate and the other to the other plate, said members having their free arms extending toward each other and overlapping when the plates are closed, said overlapping arms having registering apertures to receive the shackle of a pad lock, said apertured arms being arranged over the space formed between the diverging ends of the plates to provide for the reception of the pad lock shackle.

In testimony whereof I have signed my name to these specifications in the presence of two subscribing witnesses.
